Differences between 6x6 and 7x7

[GalPro]

I'm planning to buy next month a 5x5, and a few months after that a 6x6 or a 7x7

So should I buy 5x5 then 7x7 or but the 5+6+7 deal from v-cubes and save the 6x6 unopened for a month?

Thanks

If you plan on buying all three cubes eventually, you should buy the package deal. It is cheaper for you that way.

That's my main idea but I'm not sure if to buy them all or just 5 & 7,
is 6 worth it?

You're guessing right.
And a void cube has no parity either when you solve it corners first (but you have to be careful with the orientation of middle layer).

No, you're wrong. The void cube still has parity with your method; the difference is that your parity fix is M (or M').

You're wrong, sorry. I'm adjusting layers only at the very end of the solve. When the extreme layers are a quarter-turn apart from each other, please tell me how you define the parity case

It doesn't matter how I *define* it, it's still there. Just because you don't have a specific step or parity algorithm does not mean there is no parity for you. Parity is not a result of the method, but rather the result of solving with a (wrong) center orientation.
